To all whom. "it may concern:

Be it known that I, GIOVANNI Bosonnnnnr, a subject of the King of Italy, and residing at Terni, Italy (whose post-office address is No. 9 Via Faustini, Terni, Italy), have invented certain new and useful Improvements in Apparatus for Rolling Thin Metal Sheets, of which the following is a specification.

This invention relates to apparatus for rolling thin or medium sheets, in which continuous furnace heating is employed, and has for its object the provision of means for automatically feeding the sheet-S to the rolls.

A preferred embodiment of the invention is shown in the annexed drawings, in which:

Fig. l is a side View of the apparatus with the feeding table in lowered or receiving position; and

Fig. 2 is a similar view with the apparatus in raised or delivery position.

In these drawings, a designates a hinged cover operated by a power cylinder 6. c is another power cylinder supported by a frame 03, provided with suitable guides e for the cross-head 7'. To the cross-head f are connected two connecting rods k, which operate a hinged table 2', provided with lugs Z adapted to engage parts of the frame such as the notches m.

The table 2' is normally supported in horizontal position by a prop j carried by the connecting rode it, until the lugs Z engage the notches m, whereupon upon the continued upward stroke of the power cylinder 0 the table is tilted to permit the sheets to slide ofi onto a chute 7c and then between the rollers shown in dot and dash lines as shown in Figs. 1 and 2. Under the hinged cover a there is a driven roller shown in dot and 2: 1 up". I are u that e (3F TEBHI, ITALY.

dash lines in Figs. 1 and 2 for the feeding on to the hinged table of the pieces to be rolled coming from the furnace.

The operation of the apparatus is as follows: v

The hinged cover a opens, thereby allowing the hinged table 2' operated by the power cylinder 0 to raise, the sheets to be rolled to the level of two suitable notches provided in the columns of the rolling mill stand, in which the two lugs Z engage. When the lugs of the hinged table engage the said notches upon ope *ation of the cylinder 0, the table is tilted through a suitable angle discharging the pieces to be rolled. During the re turn stroke of the cylinder 0, the hinged table 2' and the cover a will go back to their original positions, Fig. l, the cover a providing a support for the plate so that the workman may accomplish the rolling of the pieces which have been automatically fed.

All of the said operations may, of course, be controlled by a single driving lever.

What a claim is:

Apparatus of the class described, comprising a framework, a lifting and tilting table supported on said framework, a power cylinder for lifting said table, the framework having recesses therein, and trunnions on said table adapted to engage in said recesses upon the raising of said table thereby to tilt the: table.

In testimony whereof I have hereunto signed my name in the presence of two witnesses.

GIOVANNI BOSCARELLI.
